The RTX 2080 Ti has a 250 MHz higher core clock speed and 192 more Texture Mapping Units than the R9 270X. This results in the RTX 2080 Ti providing 279.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RTX 2080 Ti has a 250 MHz higher core clock speed and 56 more Render Output Units than the R9 270X. This results in the RTX 2080 Ti providing 83.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RTX 2080 Ti was released over three years more recently than the R9 270X, and so the RTX 2080 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the R9 270X when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The RTX 2080 Ti has 9216 MB more video memory than the R9 270X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RTX 2080 Ti also has superior memory performance overall.

The RTX 2080 Ti has 424 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the RTX 2080 Ti is massively better than the R9 270X.

The GeForce RTX 2080 Ti SLI has 4352 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the RTX 2080 Ti is 7116 and the actual shader performance of the R9 270X is 1251. The RTX 2080 Ti having 5865 better shader performance and an altogether better performance when taking into account other relevant data means that the RTX 2080 Ti delivers a massively smoother and more efficient experience when processing graphical data than the R9 270X.

The RTX 2080 Ti transistor size technology is 16 nm (nanometers) smaller than the R9 270X. This means that the RTX 2080 Ti is expected to run slightly cooler and achieve higher clock frequencies than the R9 270X.

The GeForce RTX 2080 Ti SLI requires 260 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 650 Watts for the RTX 2080 Ti and a PSU with at least 500 Watts for the R9 270X. The RTX 2080 Ti requires 80 Watts more than the R9 270X to run. The difference is significant enough that the RTX 2080 Ti may have an adverse affect on your yearly electricity bills in comparison to the R9 270X.

Overview
GeForce RTX 2080 Ti is the top RTX 20 Series graphics card and considered an Enthusiast graphics card based on the Turing architecture.
Architecture
The Turing architecture represents a process shrink down to 12nm compared to 14nm Pascal. The Turing architecture provides the world's first consumer support for real-time ray-tracing technology, or RTX.
GPU
It equips a GPU Codenamed TU102 which has 4352 Shader Processing Units, 272 TMUs and 88 ROPs. The central unit runs at 1350MHz and goes up to 1545MHz in Boost mode. It also has 544 Tensor Cores for AI purposes.
Memory
The GPU accesses an 11GB frame buffer of first-gen GDDR6 memory through a 352-bit memory interface, while the Memory clock operates at 1750MHz, or 14GHz effective.
Power Consumption
With a rated board TDP of 285W, it requires at least a 650W PSU with two 8-pin power connectors.
System Suggestions
GeForce RTX 2080 Ti is best suited for resolutions up to and including 3840x2160. We recommend a top-End Processor and at least 16GB of RAM for optimal performance.

Radeon R9 270X Sapphire Toxic 2GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Tri-X", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 1000MHz to 1100MHz, while the Boost clock is now of 1150MHz. Also, the operating memory clock is now of 1500MHz.
Benchmarks indicate a 5% performance boost over the standard edition and so this card will surpass a Radeon HD 7950.
